problems/complaints in http://forums.rockbox.org/index.php?topic=16837.0 there is a known issue that on this screen the stop icon wont update, I dont know why and noone else wants to look at it, so hopefully this will force another set of eyes on it.. this is only a graphical issue... recordings still work fine git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17643 a1c6a512-1295-4272-9138-f99709370657
